Hook maneuver done properly?
-
Hey,
From general knowledge here, the hook maneuver is flexing the lower body muscles, and doing the thing with the throat. I can do “hookah” with only “hook” being audible.
But there are several problems here for a noob:
- doing it too fast leaves me out of breath
- flexing my belly (just too easy to happen by instinct) made it hard to breathe overall
- the distance between “hooks” vs normal breathing may cause hyperventillation
Why do I ask of it? Obviously I’m no fighter pilot nor ever will be. The whole story is silly:
Yesterday I got double vision and motor problems. Called a doctor, said to observe myself that day and following days. Increasing brain blood pressure (flexing muscles below the belt, lying upside down) helped with motor skills. Can “hook” help with brain blood pressure way more than flexing muscles alone? And by the way I’m all right, since 12 hours after waking up that day.
I had an old family member get insufficient oxygen to one part of their brain, happened in front of me. Scary as heck.

This is by no means medical advice. If you are interested in learning more about it, try searching for anti g straining maneuver or hick maneuver.

Way more than flexing muscles (Note, I am not a doctor). Tensing up muscles in the AGSM is intended to prevent blood pooling in the lower extremities, or limit the amount - its unlikely to ‘force’ pooled blood back into circulation. Unless you are under significant G, I doubt you would get much if any benefit out of it. The hick however directly increases blood pressure through the lung membranes. Ive used it a few times to even out dizziness with a rapid change in pressure. Improving cardio fitness should also improve the ability of the heart to increase blood pressure on demand - such as when going from lying down to standing.
Note that even with aerobatics flying, you dont get back on top of the G if you started with a weak AGSM. You need to tense up those muscles before the onset of G.

Not sure what doctor would tell you to “observe yourself” when experiencing stroke like symptoms, you should visit a hospital asap - imho

I’m a physician here in the USA, and I don’t know anything about the medical system in Poland in terms of access or cost. I wouldn’t blow off these symptoms. I strongly recommend you get in to see a doctor or other practitioner as soon as you can. Get your blood pressure checked - your symptoms could be due to either too low or too high a blood pressure - you can live with very high blood pressure for years and not have any symptoms until an episode like this. If you’re having vision changes with high blood pressure, that’s a hypertensive emergency and you need to seek medical care immediately. There are plenty of less severe potential causes (complex migraine, dehydration, orthostatic hypotension, labrynthitis) but you need to rule out the serious ones first.
Also remember: the AGSM is generally augmented by a G-suit
You’ve got to stay healthy! 4.34 is coming in 2-3 weeks…

I’m sorry to make a ruckus out of this! This is planned medicine withdrawal. It always does funny things with the heart for everyone, despite being not addictive. My blood pressure and pulse is normative. FWIW both symptoms could be related to the membranous labyrinth. It’s all gonna get out of my system in two weeks anyway.

Even with ultralight aircraft we won’t be getting anywhere near it, sadly. I measured G’s of a Polish bus, it never got over .6 G. And you don’t wanna ride a Polish bus
